Handling the LCD Panel
The following characteristics are specific to the LCD unit and are considered normal
behavior:
LCD screen may show unevenness in the brightness of certain images or may
appear different when seen from outside the specified viewing angle. Extended
shadows, or cross-talk, may also appear on the sides of screen images.
LCD screen pixels may contain black and white colored spots and color display
may seem to have changed over time.
When the same image is displayed on the screen for a long period, an after-
image may appear when the image is changed.
NOTE: Do not display the same image for a long time, change the screen image
periodically.
Using Touch Panel Correctly
Use only one finger to select an object on the touch panel.
If the touch panel receives pressure at two or more points at the same time, an
unintended object could be selected.
CAUTION
SERIOUS EYE AND SKIN INJURY
The liquid present in the LCD panel contains an irritant:
Avoid direct skin contact with the liquid.
Wear gloves when you handle a broken or leaking unit.
Do not use sharp objects or tools in the vicinity of the LCD touch panel.
Handle the LCD panel carefully to prevent puncture, bursting, or cracking of the
panel material.
If the panel is damaged and any liquid comes in contact with your skin, immediately
rinse the area with running water for at least 15 min.
If the liquid gets in your eyes, immediately rinse your eyes with running water for
at least 15 minutes and consult a doctor.
Failure to follow these instructions can result in injury or equipment damage.
WARNING
UNINTENDED EQUIPMENT OPERATION
Operate the GP unit touch panel with only one finger.
Do not activate two or more points of the touch panel simultaneously.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
